Prunus cistina growing in 2-gal containers and infested with Synanthedon exitiosa were planted in a research plot at the Ohio State University Agricultural Research and Development Center in early June, prior to moth emergence. These plants were used for evaluating efficacy of selected insecticides for reducing establishment of peachtree borer larvae. A COz compression sprayer with a Teejet SS8004 flat-fan nozzle operating at 16 psi was used to spray four 4-plant replicates/treatment arranged in a randomized complete block design. Sprays were applied 14 Jun under sunny skies at 18C with a breeze of 8-16 km/h. Each plant received 70 ml of finished spray on its lower trunk and limbs. Treatment effectiveness was evaluated 6 Sep by examining the base of each plant for exudate and frass.
